SPECIFICATION forming part of Letters Patent No. 282,892, dated August7, 1883. Application med Api-i1 23. 1883. (No model.)

To all whom tm/Ly concern:

Be it known that I, HENRY HITCHCOCK, of

Genesee, in the County of Genesee and State 5 of Michigan, have inventedcertain new and useful Improvements in Fire Escapes; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich Figure l is a perspective view of myimproved fire-escape. Fig. 2is a side elevation of the same. Fig. 3 is a longitudinal verticalsection, and Fig. 4 is a detail view of the adjustable bracket used inconnection with my improved escape. I

VSimilar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to individual fireescapes, or that class ofescapes which can be carried by a traveler in his trunk or valise, andit consists in the improved construction of a frictional fire-escape ofthat class, as'hereinafter more fully described and claimed.

In the accompanying drawings, A is the box or casing of the escape, inthe lower end of which is 'securely fastened a hook or eye, B, for theattachment of two ropes 'or straps, C and D, one of which has a loop, c,at its lower end, while the other is provided with a snaphook, d. Insideof the box or casing A are journaled three drums or pulleys, E, F, andG, the shafts of which (shown, respectively, at e, f, and g)`arejournaled in the side pieces of the casing, and provided at one end withgearwheels H,\I, and K, Awhich intermesh with one another, as clearlyshown on the drawings. In 4o the top part of the casing, if desired, maybe affixed the brake-block L, which may be regulated or controlled bymeans of a thumb-screw, M, which works in a threaded bearing in the toppart of the casing.

at its upper end, by means of which it may be N is the escape-rope,which has a hook, a,

casing A, and is wound around the several pulleys E, F, and G, inside ofthe casing, in 5o the manner clearly shown in the drawings. To preventthe rope at its several turns around the pulleys from wearing againstitself in using the apparatus, I provide the inside of casing A withguide-blocks P, by means of which the 5 5 several windings of the ropeare properly spaced, so as to make one turn run free of another.

I prefer to use this escape in connection with the adjustable bracketwhich is shown in Fig. 6o 4 of the drawings, one of the arms, Q, ofwhich is made extensible, so that it can be adj usted to the width ordepth of any windowcasing by means of the screw R. Each of the two armsof the bracket is 'provided with a 65 dog, S, which, by .bearing againstthe wood of the window-casing and working with its point into the same,will hold the bracket securely in place, 'with its outer end projectingthe proper distance from the wall to make aperson 7o descending swingfree of the building when the apparatus is in use.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, in an individualfrictional nre-escape, of the casing A, having hook or l eye B, providedwith ropes or straps C D, adapted to support or hold the person usingthe apparatus, drums or pulleys E, F, and G, provided with theintermeshing gear-wheels H, I, and K, escape-rope N, having hook n, andguide-blocks P, arranged inside of casing A, as shown, and adapted toproperly space rope N in its turns or windings around the severalpulleys, the whole constructed and combined to operate substantially inthe Inanner and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature '9o in presence of two witnesses.

HENRY HITCHCOCK.
